Rangers starter Tommy Hunter could miss up to six weeks of action after suffering a Grade II right groin strain. He is expected to begin the season on the disabled list. "I can't do anything about it," Hunter said. "I can't help the team on the disabled list. I want to be there Opening Day and I'm not going to. I just have to get healthy and get back out there. It's tough." Michael Kirkman and Dave Bush are the leading candidates to replace Hunter in the team's starting rotation. Hunter, 24, suffered the injury during an appearance against the Reds on Thursday.
